    the course Their rated ability did not increase significantly overall although those students who scored poorly in the pre course assessment scored significantly higher in the post course assessment In general male students felt more confident than female students about their responses to quantitative information although their rated scores were similar No background data could account for variation in initial performance or change in performance Improvements in lower scoring students are encouraging as are increases in student perceptions of ability However the large number of poorly performing students in both the pre and post course assessments and the disconnect between how students thought they performed and how they were scored means that actual performance may not increase with increasing perceptions of ability Students may need more opportunities for feedback to confront the disparity between their perceptions and the reality of their lack of success in interpreting quantitative information Format html Primary or BEN resource type Teaching strategies guidelines Discipline Specific Core Concepts Ecological Core Concepts The science of ecology Statistical analysis Ecological Core Concepts The science of ecology Life science discipline subject Ecology Keywords research practitioner TIEE pedagogy student active assessment analytical skill graphing skill graph interpretation quantitative ability Audience Undergraduate upper division 15 16 Undergraduate lower division 13 14 Intended End User Role Teacher Language English Educational Language English Pedagogical Use Description Quantitative skills are critical to students understanding of ecology and while these skills are usually taught in ecology courses they are rarely assessed This study documents differences between students perceptions of their performance in pre and post tests and their actual performance The article is a useful resource for faculty who are teaching these skills since the authors describe their results and recommend strategies for instructors to successfully teach these skills The article is also a useful
